Since we seek the action of force to push up box 1, the students observes an unbalanced upward force on Box 1 in procedures 4 and procedure 5.

In what procedures did students observe an unbalanced upward force on Box 1?

Generally, In procedure 4 we added another mass to the box two, therefore, causing box one to experience an upward force.

Therefore, students observe an unbalanced upward force on Box 1 in procedure 4.

Procedure 5 we remove masses from box 1 resulting in box 2 becoming heavier, pulling it down.

Therefore, students observe an unbalanced upward force on Box 1 in procedure 5.
